When changing the trigger type in the trigger editor, properly redraw the control
Summary: Ref T13269. I refactored this late in the game to organize things better and add table cells around stuff, and accidentally broke the relationship between the "Rule Type" selector and the value selector.
Test Plan: Switched rule type selector from "Change Status" to "Play Sound", saw secondary control update properly.
